Table 38: POWER LED Description (continued)
Possible Cause and Corrective Action Meaning LED State LED Status
If a red alarm condition occurs, issue the
show chassis alarms command to
determine the source of the problem.
•
Verify that the AC power cord and/or
DC power supply cable is not damaged.
If the insulation is cracked or broken,
immediately replace the cord or cable.
•
Verify that the source circuit breaker
has the proper current rating. Each
power supply must be connected to a
separate source circuit breaker.
•
Ensure that the power socket you are
plugged into is in working condition.
•
Connect the power supply to a different
power source with a new power cord
or power cables. If the power supply
status LEDs indicate that the power
supply is not functioning normally, the
power supply is the source of the
problem. Replace the power supply with
a spare.
NOTE: If the system temperature exceeds
the threshold, the Junos OS shuts down
all power supplies so that no status is
displayed.
The Junos OS also can shut down one of
the power supplies for other reasons. In
this case, the remaining power supplies
provide power to the services gateway,
and you can still view the system status
through the CLI.
Indicates that the services
gateway is not receiving
power.
